Introduction

2.1 General

INGVAR is intended for use in high-voltage substa-

tions and industrial environments, for laboratories and

testing purposes. INGVAR consists of a Control Unit

equipped with a control panel and a Current Unit. The

units are portable and easy to connect.

INGVAR is designed to generate short-duration cur-

rent, and is protected from overheating. Under special

circumstances, INGVAR can generate up to 5,000

amperes.

The Control Unit controls the current output (gen-

eration) from the Current Unit and is equipped with

sophisticated measurement facilities. The Control Unit

can sense the phase angle and adapt subsequent gen-

eration operations so that they all start at the current’s

zero-cross-over points. This ensures minimized DC

offset in connection with starting.

Current generation

Current can be generated in many ways:

▪

Continuously.

▪ During a preset maximum time.

▪ As long as you press a button.

▪ Until an external signal activates the stop input.

▪ At a lower current (I/30) to avoid unnecessary heating

of the object being tested while the current is being

adjusted.

▪ In pulses (both pulse duration and between-pulse pause

are user-deﬁnable).

The measurement section

contains/provides

▪ Timer.

▪ Digital ammeter (true RMS).

▪ An additional channel for measuring a voltage or a

second current.

▪ Direct display of the turns ratio of a current transformer.

▪ Provisions for measuring phase angle Z, P, R, X, S, Q and

power factor (cos ϕ).

▪ Currents and voltages expressed (if so desired) as

percentages of nominal values.

▪ Fast-acting hold function. Measured values can be frozen

in response to a signal arriving at the stop input and/or

when the current is interrupted.

In addition to its normal working mode, there are spe-

cial INGVAR settings supporting the following types of

testing:

▪

Testing of direct acting automatic reclosers.

▪ Testing of sectionalizers.

Even though INGVAR features outstanding versatility,

it is very easy to use because:

▪

You can start generation whenever desired.

▪ You can repeat a measurement by simply pressing a

button. It is not necessary to clear the display ﬁrst.

▪ You can save different settings for INGVAR in ten different

memories.
